Matrix2png

Matrix2png is a simple but powerful program for making visualizations of microarray
data and many other data types. It generates PNG formatted images from text
files of data. It is fast, easy to use, and reasonably flexible. It can be used
to generate publication-quality images, or to act as a image generator for web
applications. Our group has found it useful for imaging all kinds of matrix-based
data, not just microarray data.

Documentation

NOTE! Matrix2png generates PNG (portable network
graphics), not gifs or jpegs. The PNG format is supported by the major
web browsers as well as image processing software such as Adobe
Photoshop, Macromedia Fireworks, etc. Read about the PNG format
here. For many users,
the web
interface to matrix2png will suffice. If you want to install and
